able transverse member I3. mring blocks ai and it have pins at passing' 55 through them and the pins extend from either side of the blocks a sufiicient distance to engage in the openings 33 of members I0 and Il. The pins are slidably fitted in the openings.' By means of the arrangement described. the blocks are retained in members 8l and 3l in a vertically movable relation.

Members 30 and 3l are pivotally supported in frame member i3 by means of Ipins 35 which pass through the former and the walls of member ld.

Pivotally mounted upon pins 34 and 35 are link members 36 and 11 which are pivotally connectedbypins $8.

Links 36 and 31 are so proportioned in length as to act as a toggle mechanism by means of which the blocks 21 and 2l, together with roll i5, maybe elevated or lowered.

Dotted outlines at the left links"move toward'a position o! alignment be tween pins 3l, 38 and 15 which would be the position of greatest possible distance between pins 34 and 35, corresponding to the innermost; position of roll l5. Movement of pins l! toward thecenter of the wringer would obviously result' in pivotal movement of links 36 upon pins Si as outlined at the lett in Fig. l and relative folding and upward movement of 31 to elevate blocks 21 and 28, together with roll ll.

It has already been noted that upper frame i3 is removable from the lower frame and that pins 35 are mounted in the upper frame.

In order to provide that downward vertical movement of roll i5, as brought about by the mechanism described, be eective to produce and maintain pressure between rolls it and ib it is necessary thats' means for locking the upper frame in position upon end members il' and i2 be provided.

For this purpose I provide notches 32 in members 30 and 3i. The lower lips of these notches are adapted to engage plus HB which are secured in members il and i2 as shown.

The notches and pins described are obviously adapted to act as a latching means whereby the upper frame is locked in xed position relative to the lower frame. Thus the pressure load between rolls M and i5 is carried by pins 35% and dll through members 2 1 and Z8.

However this latching means is only efectlve to hold the top frame in place when it is forcibly held in latched position, as will be apparent when it vis. observed that the pins ed, and the lips of notches engaged therewith, are oflset with respect to lines passing through pins 35 and lying parallel theend walls o! frame Il.

With the parts in the solid line position at the left in Fig. 1, with member 3l unsupported, upward pressure on the` top frame I3 will force the lip 32 to back away from the pin 4B and there will be no latch connection between the Wringer frames. 1

The parts are so arranged that a part of any pressure applied on pins l! tending to move them outwardly is distributed through pins 34 to members 3l and 32- to force them outwardly. whereby they are prevented from backing away as above n oted, and the parts are held-.in latched relationship. 1

Further, it will be understood that with the pins 36 confined by slotsv 33 in members 3B and 8l, initial outward movement of pins 38 is absorbed in moving members Il and 3| toward the pins 48 and that no pressure is distributed to the rolls imtil the outward movement of mem- 4in Fig. l indicate. that when the pin 38 is moved outwardly um u and ai a/errested, after which the pim u ateforced toffollow the .slots 33 in downward direction, thus forcing the rolls downward into pressure POSIOD- 'l It will now become apparent that with the top frame I3 in position on the lower lframel when pins il are forced outwardly, the mns will be forced downwardly 4in opposition to spring llwhile at the same time pressure will be applied to members 3l to hold them latched, thus holding the top irame'in fixed position on the lower'frame. On the other hand. if pressure is removed from pins Il. the rolls will be free to move upward responsively to spring il and at the sometime the supporting pressure on members Ii will be removed so that the lips l2 may escape. from pins 4l and the top frame will be free to move with respect to the lower frame. Bearing in mind that identical movements of the parte shown at the right in Flgr.` 1 take piace simultaneously with those just described, it will be clear that the 'escape movement will result in release of frame i3 `#rom uprlghts Il and I2 with the iinai result that roll Ii is no longer h el'd inabutment with roll i4, and that frame Il, together with attached mechanism and roll Il may be removed from the lower frame. Theutility of the described mechanism will be ex- Dlained shortly.

To produce inward and outward movements of pins 38,1 provide a mechanism as follows:

Reference to Fis. 3 will disclose ansulated band bars 4I disposed upon either side of frame I3, each having ashank portion 42 extending within the frame. lThe 'shank portions are rotatably mounted'in the side walls of the frame and are further supported and j ournalled in a supplemental-y interior, frame structure comprising members d8 which areso fashioned that their end portions u'lie adjacent the side wens or frame l; where they are `supported upon pins I5.' Members es have named openings at M which are so'proportioned as torotatably receive elonzatedhub portionsof disk members li. The disksv aresecured to shank portions 42 by means of pins el.

Additional disks Il are supported on the shank portions adjacentgthe disks and have a pin Il joining them at on oiieentral position.

An oppositely Il pessesthroush disks 0B and Ill, thus forming a connection'between disks It and the shanks of hand bars 4i whereby the assembly operates as a unit.

v Pivotaliy mounted upon pins A! and 5I are` outwardly disposed members il having their outer ends supported byzpins 52 which slide in slots 53 formed in members 43.

angulares um: members u are pivotaliy'connected with link s il and 3 8 by pins 52 and 3l.

Disks 4S are provided with slots 4l' extend ing substantially 180 degrees in the disks, and

pin Il! operates in slots. The slots are so disposedthat when arms 4l are disposed as,

shownin solid lines, and pin Vil is disposed toward thought, the end of .the slot is' engaged with the pin in such position that continued counterclockwise rotation of the arms would torce the pin upward.

It will be noted that when the parts are in locked position the pins I and Il rest somewhat beyond a'dead' center position with respect tu the pins 53 and :haaks 42, and that a pin 5l, secured in members N. i'orms an abutment adapted to Aprevent movement of arms 4I and v mcchani'sm`beyond the position noted.

fil

amasar With parts in the latter described position it will be obvious that a slight downward manual pressure applied to the end of arm El will bring about counterclockwise movement of pin 50, and through this, disks 48 to displace both pins out of their pre-center position and allow their continued rotation to unlock the mechanism as formerly described.

During the above described release movement the pin 50 moves in the slots J6', and finally arrives in position adjacent the opposite ends of the slots.

It will be apparent that the mechanism may be easily re-assembled into locked position by pressing downwardly upon frame I3 while at the same time urging the arm 4l in clockwise direction whereby roll I5 is forced downwardly upon roll I4, notches 32 are positioned opposite pins 40 and members 2l and 28 are forced outwardly against the pins in such a manner as to force them into hooked engagement therewith. Final rotation of the hand arm to the limit of its movement, as controlled by pin 55, replaces the linkage in position where the force of spring I9 is opposed by the pins 49 and 50.

After the locking operation is completed, arms 4| are returned toward the left to the solid line position and they are then available to release the mechanism as above explained.

What I claim`is: f
